Newbie, Supercharger questions

Fists things first, IM SORRY. I am going to ask stupid questions, feel free to laugh at me because I understand where you guys are coming from. Im a diesel guy who has can turn a pretty mean wrench. BUT new to the gas world so bare with me.
Okay well here it goes, I just bought a 98 taco with the 3.4. It was un-supercharged from the factory. I purchased it from my cousin and he put a Trd supercharger on it like 10,000 miles ago. Now I can tell its running really lean(obvious) Now I was going to purchase the URD 7th injector kit. I know this will help but I was just curious what else I could do to give the truck some more umpff. Or what you guys thought of the Urd kit, if there are cheaper ways or other brands.

P.S. I have a 1995 ford bronco with a 98 cummins disel pushing over 500hp, so I know what Egt's and timing is all about. Just dont know how to adjust it or what are safe ranges for a Taco! So let the beating begin!!

Oh and welcome to the forum.

 

Thank you for the response. I Just pulled the truck in my shop for the first time and looked under the hood and found a URD box with wires coming out and a small rubber hose thats about 6'' long and doesnt connect to anything. The wires go through the firewall and im assuming the to computer, but the little vacume hose like thing is just loose. I think the box is either a URD Additional Injector Controller / Timing Calibrator or
URD Mass Air Flow Fuel & Timing Calibrator. But i cant tell the difference, Also the guy I got it from said it has "everything except the actual injector" but I dont really beleive that.... I know that he took the whole intake/supercharger off the totaled truck and just put that one on this truck. So im still not sure what im gonna need for my URD 7th injector kit

 

Okay I called and talked to URD and explained the situation. Im buying the whole 7th injector kit and throwing away the other shi%. They were very helpful. Now what size pully should I get for the supercharger to go with the 7th injector?

 

i m going with the 2.200 pulley when i buy my URD 7th inj. kit. they say its good for street use with 91 octane. i figured it be the best DD without blowing my shit up. the next smaller one needs 93+ octane. but i m way excited to buy all that shit after i get my tax refund!!! nothing like some more HP. cant wait to see what other fast cars i can surprise with my taco on 35s haha
